I am a couple of weeks away from my first PP purchase, which takes the form of an Aquanaut 5167. Very excited indeed - the 5167 is the most versatile PP; IMHO the tropical strap goes with any attire.

Would be grateful if you kind folks could provide provide some answers to the following:

1. Care to share any good reviews / write-ups on the Calibre 324? I have done some googling but have found little information, which is strange since it seems like the 324 is one of PP's core movements...

2. Any difference between the older movements bearing the Geneva Seal and those bearing the Patek hallmark?

3. Anything else that I should be aware about the Calibre 324 / Aquanaut 5167?
